+
+The GL module incapsulates ROOT's interface to the OpenGL rendering
+engine and provides the following functionality:
+
+<ul>
+
+  <li> management of system-resources;
+
+  <li> frequently used utility classes;
+
+  <li> base-classes for shapes, scenes and viewers;
+
+  <li> concrete implementations of shapes needed by TGeo package;
+
+  <li> concrete implementations of scenes and viewers including the
+  GUI components;
+
+  <li> specialized plot-painters for GL rendering of TH2, TH3, TF2 and
+  TF3 object as well as parametric surfaces.
+
+</ul>
